However, when hoisting on site, the installation height of some special workpieces will exceed the maximum lifting height of the gantry crane. In such cases, other cranes with high lifting heights are used in the factory. If there is no such equipment in the factory, it must be rented. Caterpillar cranes with large lifting heights, or floating cranes to meet work requirements, greatly increase the cost of hoisting and reduce the utilization rate of equipment for enterprises

The invention discloses a height-increasing suspension beam capable of increasing the lifting height of a large-scale gantry, comprising a vertical suspension beam and a horizontal suspension beam, the vertical suspension beam is located above the horizontal suspension beam, and the left end of the horizontal suspension beam is connected to the vertical suspension beam The bottom of the hanging beam is connected, and there are three lifting points on the horizontal hanging beam, which are lifting point A, lifting point B and lifting point C respectively. Lifting point A, lifting point B and lifting point C are located in the same plane and the three cooperate A plane triangle is formed, and a plurality of counterweight boxes connected to the bottom of the horizontal suspension beam are arranged under the right half of the horizontal suspension beam. The invention also discloses a large-scale gantry crane, which includes an upper trolley, a lower trolley and the above-mentioned height-increasing suspension beam. The lifting point A is connected with the hook of the lower trolley, and the lifting point B is connected with a hook in the upper trolley. Point C is connected to another hook in the upper trolley. The invention improves the lifting height and lifting capacity of the existing large-scale gantry cranes, and improves the utilization rate of enterprise equipment.
Description
technical field [0001] The invention relates to a gantry crane, in particular to a height-increasing suspension beam and a large gantry crane which can increase the lifting height of a large gantry crane. Background technique [0002] Large-scale gantry cranes generally have two trolleys: an upper trolley and a lower trolley. The upper trolley has two hooks, and the lower trolley has a hook. The lower trolley can pass through the lower part of the upper trolley. The existing large-scale gantry crane has a high lifting height and a large lifting weight. Through the lifting of the hooks of the upper and lower trolleys, it can not only meet the work requirements of various heavy loads, but also undertake the lifting and handling of many large-scale equipment. However, when hoisting on site, the installation height of some special workpieces will exceed the maximum lifting height of the gantry crane. In such cases, other cranes with high lifting heights are used in the factory. ...
